A bathroom ventilating device includes one or more air inlet openings formed in a ceiling of a bathroom for introducing an air into the bathroom, and an air evacuating device disposed on a floor of the bathroom for evacuating odour and moisture from the bathroom. An air drawing device is attached to the ceiling of the bathroom and includes a fan aligned with the air inlet opening of the ceiling for drawing the air into the bathroom for effectively circulating and drawing the air out of the bathroom and for effectively circulating and introducing the fresh air into the bathroom and for effectively removing the odour and the moisture from the bathroom.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a bathroom ventilating device, and more particularly to a bathroom ventilating device including an improved air circulating effect for effectively circulating and drawing the air out of the bathroom and for effectively circulating and introducing or providing the fresh air into the bathroom and for effectively removing odour and moisture.

2. Description of the Prior Art

Typically, in a bathroom, a great humidity or moisture may generally be generated, and a bad odour may thus be generated. For removing the odour and the moisture, various kinds of air ventilating devices have been developed and attached to or disposed in a bathroom for filtering the air in the bathroom and for decreasing the odour and the moisture.

For example, U.S. Pat. No. 5,727,262 to Littlejohn discloses one of the typical bathroom ventilators for disposing on top of a conventional toilet tank or for mounting onto the wall, and comprising a fan or blower for drawing the air in the bathroom through an absorbent material and a number of removable fumigating filters.

However, the fan or blower may only be used to draw and to circulate the air in the bathroom only, but may not be used to draw the fresh air into the bathroom and also may not be used to draw the odour and the moisture out of the bathroom, such that the air may not be suitably or effectively circulated within the bathroom, and such that the odour and the humidity or the moisture may not be quickly removed.

U.S. Pat. No. 5,862,981 to Weng discloses another typical bathroom ventilation control device for disposing in a bathroom and comprising a controller connected to a fan motor in order to change the rotational speed of the fan motor.

However, similarly, the fan or blower may only be used to draw and to circulate the air in the bathroom only, but may not be used to draw the fresh air into the bathroom and also may not be used to draw the odour and the moisture out of the bathroom, such that the odour and the moisture may not be quickly removed. In addition, the fan or blower is disposed on top of a ceiling, but the humidity or moisture is normally found in the lower portion of the bathroom mostly such that the humidity and the moisture may not be effectively removed by the typical bathroom ventilation control device.

U.S. Pat. No. 6,177,575 to Smith discloses a further typical bathroom ventilator inlet having an air evacuation opening to remove air from a bathroom, and having a central vacuum system for acting as a suction source. The typical bathroom ventilator inlet should be disposed above or close to the seat cover or the toilet for allowing the user to easily fetch the toilet paper.

However, similarly, the humidity or moisture is normally found mostly in the lower portion of the bathroom such that the humidity and the moisture may not be effectively removed by the typical bathroom ventilator inlet. In addition, the fresh air may not be drawn or introduced into the bathroom to quickly dissipate the odour and the moisture.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional bathroom ventilating devices.
